Extract

A newly discovered Helicoprion specimen from the Patlanoaya Formation, State of Puebla, represents the southernmost finding of this genus of edestoid-shark in the Western Hemisphere. It was found in sediments assigned to the upper part of the Early Permian, based on its association with Perrinites hilli, an index ammonoid for the Leonardian age.
